PIN-PROTECTOR.

Patented Nov. 26, 1912.

Serial No. 684,597.

To all whom it may concern:

Be it known that I, AN'rHoNnY BURK, a citizen of the United States,residing at Grindstone, in the county of Fayette and StateofPennsylvania, have invented a new and useful Pin-Protector, of whichthe following is a specification.

The objects of the present invention are to provide a shield for thepoint of a hat pin, a tie pin or the like, the shield being soconstructed that it will automatically grip the pin and house the pointthereof, novel means being provided for preventing a displacement of theshield from the pin.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 shows the invention in side elevation, appliedto a pin; Fig. 2 shows the inventlon in longitudinal section; Fig. 3 isa transverse section on the line 33 of Fig. 1; Fig. 4 is a perspectiveof one of the constituent members of the device; Fig. 5 is a perspectiveof the other of the constituent members of the device; and Fig. 6 is asectional detail enlarged from Fig. 2, showing the pin in place. Fig. 7is a fragmental side elevation showing a slight modification in the pin.

In carrying out the invention there are provided a pair of membersdenoted gen erally by the numeral 1, each member 1 consisting of ahemispherical point-shielding part 2 and a trough-shaped pin-grippingpart 3. The members 1 are provided intermediate their ends withoverlapped ears 4, through which are passed pivot elements 5. One of thepoint-shielding parts 2 is of larger diameter than the other, so thatthe parts may interfit, when the members 1 are swung upon their pivot-a1connections 5. As shown to best advantage in Fig. 3, the pingrippingparts 3 may be provided with teeth 6, adapted to engage the pin 7, thehead of the pin being denoted by the numeral 8.

Projecting inwardly from one of the point-shielding parts 2 is a tube 9.A fiexible spindle 10 projects from the other pointshielding part 2 andenters the tube 9, the

members 9 and 10 constituting overlapped elements located within thepoint-shielding parts 2. Surrounding the tube 9 and the spindle 10 is ahelical compression spring 11, hearing at its ends against thepoint-shielding parts. The tube 9 and the spindle 10 obviously serve toretain the spring 11 in place.

The point of the pin 7 is thrust between the pin-gripping parts 3,theteeth 6 engaging the pin. The spring 11 serves to thrust thepoint-shielding parts 2 apart, and to thrust the pin-gripping parts 3together, to hold the device upon the pin. In the tube 9 there areopenings 14, alined with the pin-gripping parts 8. Through the openings14 the point of the pin 7 may be thrust, and when the point of the pinis engaged in the openings 14, the pin will form an abutment for thespindle 10, as shown in Fig. 6 and it will be impossible to force thepointshielding parts 2 together, and release the pingripping parts 3from the pin 7, until the point of the pin is withdrawn from the openings 14. Moreover, the convolutions of the spring 11 are so positioned,as clearly shown in Fig. 6, that they will engage the pin, and preventan accidental withdrawal of the pin from the openings 14.

If desired, the pin 50 may be roughened in any desired manner asindicated at 51, to interengage the teeth 6 of the gripping parts 3.

Having thus described the invention, what is claimed is 2- 1. A deviceof the class described comprising a pair of members pivotally connectedintermediate their ends, the members terminating at one end incooperating pingripping parts and at the other end terminating incooperating point-shielding parts; a tube projecting from one of thepointshielding parts; a spindle projecting from the other of thepoint-shielding parts and adapted to register within the tube; and aspring surrounding the spindle and the tube and abutting terminallyagainst the pointshielding parts; there being an opening through thetube, alined with the pin-gripping parts, and adapted to receive a pin,whereby the pin will serve as an abutment for the spindle and prevent aseparation of the pin-gripping parts, the spindle terminating adjacentthe opening.

2. A device of the class described comprising a pair of memberspivotally connected intermediate their ends, the members terminating atone end in cooperating pingripping parts and at the other endterminating in cooperating point-shielding parts; a tube projecting fromone of the point-shielding parts; a spindle projecting from the other ofthe point-shielding parts and adapted to register within the tube, the

tube being provided with an openin alined with the pin-gripping parts,and adapted to receive the pin, whereby the pin will constitute anabutment for the spindle and prevent a separation of the pin-grippingparts, the spindle terminating adjacent the opening; and a helicalspring surrounding the spindle and the tube and abutting against thepoint-shielding parts, the convolutions of the spring being arranged toengage the pin, to hold the pin in the opening.

3. A device of the class described comprising pivotally connectedpoint-shielding parts provided with cooperating pin-gripping members andhaving elements in their interiors which project toward each other, saidelements having faces adapted to abut againsto-pposite sides of a' pinwhereby the pin will prevent a separation of the pingripping members;the pin-gripping memhers constituting means for guiding the pin betweensaid faces.

4. A device of the class described comprising a pair of memberspivotally connected intermediate their ends, the mem bers terminating atone end in cooperating pin-gripping parts and at the other endterminating in cooperating point-shielding parts; overlapped elementsprojecting from the interiors of the point-shielding parts, one of saidelements being provided with 40 an opening alined with the pin-grippingparts, and adapted to receive a pin, whereby the pin will constitute anabutment for the other element, and prevent a separation of thepin-gripping parts, the other of said elements terminating adjacent theopening; and a spring surrounding said elements and abutting against thepoint-shielding parts, to maintain the pin-gripping parts incooperation, certain of the convolutions vof the spring being locatedupon opposite sides of the opening thereby to engage the pin, when thepin is in the opening, and to hold the pin against withdrawal from theopening. 7 In testimony that I claim the foregoing as my own, I havehereto aiiixed my signature in the presence of two witnesses.
